I'm running MacDraft Professional 5.6.5 and when applying the requisite patch prior to installing version 6.0 the installation errors out when trying to change the permissions for content, info.plist, MacOS, Content/MacOS/MacDraft, Content/Resources, MacDraft.rsrc

I have tried to update MacDraft Pro several times from 6.0 to 6.0.5. The updater runs and says that all is OK however the new application will not open.
